Degassers, degassing systems, and methods of using degassers to remove gas molecules entrapped or dissolved in a processing liquid. The degasser has a vacuum chamber with one or more walls; one or multiple inlets and one or multiple outlets through which the liquid is respectively passed into and out of the vacuum chamber, the inlet(s) and the outlet(s) penetrating the one or more walls; one or multiple separators located inside the vacuum chamber and being pervious to the gas molecules but impervious to the liquid; at least one vacuum for applying through a vacuum port a pressure differential across the separator(s) to cause the gas molecules to leave the liquid and to permeate through the separator(s) thereby removing the entrapped or dissolved gas from the liquid; and optionally one or multiple feed lines in fluid communication with the inlet(s) and two or more than two separators.

A fuel module for pumping and filtration of a fuel in a fuel system includes a flow housing, and each of an electrically powered pump, a first cartridge filter, and a second cartridge filter in sealed, direct engagement with the flow housing. The fuel module is applied in a low pressure fuel circuit feeding fuel to a high pressure fuel circuit for pressurization to an injection pressure. Electronic closed loop control techniques for the pump are also disclosed.

An object of the present invention is to provide a chemical liquid purification method which makes it possible to obtain a chemical liquid having excellent defect inhibition performance. The chemical liquid purification method according to an embodiment of the present invention is a chemical liquid purification method including obtaining a chemical liquid by filtering a substance to be purified containing an organic solvent by using two or more kinds of filters having different pore sizes, in which a supply pressure P.sub.1 of the substance to be purified supplied to a filter F.sub.max having a maximum pore size X.sub.1 among the two or more kinds of filters and a supply pressure P.sub.2 of the substance to be purified supplied to a filter F.sub.min having a minimum pore size X.sub.2 among the two or more kinds of filters satisfy P.sub.1>P.sub.2.

A cleaning system includes a planar material beneath a soiled grow table. The planar material is non-porous except for a drain. Above the planar material is a plate layer including at least two layers of runners arranged in a grid where each successive layer is offset at an angle with respect to the grid of a previous layer. The plate layer rests upon the non-porous material. An upper layer covers the plate layer and has a plurality of holes. A roller table is provided for slideably supporting the grow table. Nozzles are positioned over the grow table and is/are interfaced to a pump for receiving and spraying liquid from the pump downwardly towards the grow table. The liquid and impurities (e.g., soil, leaves) fall to the upper layer and through the plurality of holes for cleaning and filtering the liquid before the liquid is returned to the pump.

Provided is a condensation device capable of removing water vapor from a larger amount of gas without making a size larger than in related art. A condensation device 700 according to the present invention includes an outer cooling unit 720 including one or two or more inner tubes 722, an outer tube 724 located outside the one or two or more inner tubes 722, and a first flow path 726 through which a first cooling medium passes between the one or two or more inner tubes 722 and the outer tube 724.

An apparatus and methods for the separation of macroscopic solid body particles (SBPs) from a fluid stream contained in a conduit, such as a hose or pipe. The method involves utilizing a particle separator having a fluid inlet port connected to a fluid inlet conduit and a fluid outlet port connected to a fluid outlet conduit to change the direction (and optionally the velocity) of the fluid stream within a lumen of an enclosed vessel component of the particle separator sufficiently to permit SBPs to fall by gravity (and/or to descend due to inertia) into a removable receptacle within a bottom portion of the vessel component while directing the flow of cleansed fluid to the fluid outlet port of the particle separator.

A filter element for cleaning an operating liquid of a machine tool is provided with a pressure-stable jacket permitting flow therethrough. A filter medium is arranged in the pressure-stable jacket. A first end disc and a second end disc are seal-tightly connected to opposite ends of the filter medium. The filter medium surrounds an inner raw-side cavity. The pressure-stable jacket surrounds the filter medium and is connected fixedly to the first and second end discs. The first end disc has an inlet opening for the operating liquid. The second end disc has a drainage opening provided with a releasable closure element that closes the drainage opening.

A method for making a filter membrane includes: forming a polymer layer; applying a plurality of nanoparticles on the polymer layer, the nanoparticles being self-assembled to form a closed pack arrangement on the polymer layer; heating the nanoparticles such that a portion of the polymer layer contacting the nanoparticles is softened so that the nanoparticles are sunk into the polymer layer; and removing the nanoparticles from the polymer layer so that the polymer layer is formed with a plurality of pores penetrating the polymer layer and being arranged in a honeycomb pattern.

A separation device includes an orbiting mechanism including an outer peripheral surface whose partial region is immersed in a liquid to be treated flowing through a first flow path and which orbits to cross a liquid surface, and attracting oil floating on the liquid surface to separate the oil from the liquid to be treated, a first scraper removing the oil attracted to the outer peripheral surface, an abrasive grain accumulation part provided on a downstream side of the first flow path with respect to a position where the outer peripheral surface is immersed, and in which non-magnetic abrasive grains having larger specific gravity are accumulated, and a liquid-to-be-treated discharge structure provided on the downstream side of the first flow path, and separates the liquid to be treated in the first flow path from the abrasive grains and discharges the liquid to be treated from the first flow path.
